Application filed. June 13, 1922.

T all whom it may concern Be it known that 1', .Howino L. INounsoLL, acitizen of the United States, residing at iVhite Plains, county orlVestchestcr,

State of New York, have invented a certain new and useful Improvement inCast- Steel Platforms, of which the following; is a full, clear, andexact description, such as will enable others skilled in the art towhich it appertains to make and use the same, reference being had to theaccompanying drawings, forming part of this application.

My invention relates to railway rolling stock and in particular to carsarranged with a primary or self-generating power unit.

My invention consists in imprmements in the body framing which adapt thelatter for the motor arrangement.

The main object of my invention is to make the motor accessible at alltimes trom the interior of the car.

In the accompanying; drawings. which illustrate a selected embodiment oimy invention Figure 1 is a top plan v w of a car truck and body platformmounted thereon and the motor which is supported by the truck frame.

Figure 2 i tion through in Figure 1.

Figure 3 is a transverse section taken si'ibstantially on the line 33 ofFigure 2.

The car truck is provided with wheels 1. journal boxes 2, equalizer bars3, and springs l of usual construction. The truck frame preferably asteel casting: and is provided with journal b0): pedestals side sills6.. one sills T, and longitudinal center sills R. Formed integral withcenter sills S is the base and crank case 9 of the motor l0,ronstitutiug; the car power unit, This motor is here shown as aninternal combustion engine o'l familiar type and with its base extendingup. ardly a substantial distance above the truck frame.

The car body underi rame is indicated by aplattorm casting having theusual side a vertical longitudinal secs D a the center or the partsshown Serial No. 568,030.

sills 11, end sill l2, bolster l3, transverse member 16 and longitudinalcenter or draft sills ll. The latter are spaced a substantial distancefrom each other to receive the iuwrardly extending motor 10 between themand the bolster 13 and member 16 are similarly spaced. The sills,bolster and cross member forming the sides of the motor re ceivingopening are flanged, as indicated. to suitably reinforce this portion ofthe platform.

'llhe car side is indicated at 1.5 and it will be understood that thecar body is carried by the platform or under-frame casting in the usualmanner.

I contemplate all such modifications in the details of the constructionfall within the scope of the appended claims.

What I claim is:

1. in a railway car, a truck frame, a motor mounted on said truck frameand extending upwardly therefrom, and a car body under-frame including aone-piece platform casting having longitudinal draft or center sills andtransverse members above said truck frame spaced from each other toreceive said motor between them. said sills and members being flanged toreiutm'ce the. casting about the opening lil'OVlilGfl tor the motor.

2. in combination, in a railway car, a truck ti'ramc, a motor mountedthereon, a body plat-form. supported, on said truck frame, consisting:of a one-piece casting provided with an end sill, with longitudinalflanged members oxteurlinu' rearwardly therefrom and spaced a sulrantial distance from the sides of the d )rm. and with flanged membersextending: transversely oi the platform behind said end sill. saidmembers being spared so as to provide a. reutrally located oocniur'therebetweeu to permit the projection oi said motor above the platformwhereby the motor opening in the platform will be surrounded by the mainmembers of the platform casting.

In testimony whereof I hereunto afiix my signature this 25 day of May,1922.

HOWARD L. INGERSOLL.
